additional C—H•••π(ring) interactions into the full 3-D structure. To obtain a structure-activity relationship, the DFT-NBO analysis is performed to study the intrinsic electronic properties of the title compound. Molecular modeling studies were also conducted to examine the binding affinity of the compound for the SARS-CoV-2 main protease enzyme and to determine intermolecular binding interactions. The
N-Hydroxy-(5-,6-,7- or 8-alkoxy)-1- or -2-naphthalinalkanamines, e.g. of formula I
(R1 = hydrogen, C1-8alkyl or C4-6cycloalkyl, R2 = C1-6alkyl, R3 = hydrogen or halogen, and A is C1-6alkylene) and their physiologically-hydrolysable and -acceptable esters. The said compounds are lipoxygenase inhibitors.
substrate specificity for 5-lipoxygenase and the known stereochemical course of the reaction, a hypothetical model of the enzyme active site was developed and used to design 2 types of selective inhibitors of 5-lipoxygenase. Both inhibitor types used aromatic rings in place of (Z)-olefins of the substrate and were designed to mimic the nonpolar end of arachidonic acid. One inhibitor type used a carboxylic-acid
